Cathepsin proteases are crucial in cell death and cancer progression. This review explores recent advancements in understanding cathepsin regulation, focusing on lysosomal membrane permeabilization and apoptosis in cancer research.

Area of Science:

  • Biochemistry
  • Cell Biology
  • Molecular Oncology

Background:

  • Cathepsin proteases play vital roles in cellular homeostasis and disease.
  • Lysosomal Leakage (LL) and Lysosomal Membrane Permeabilization (LMP) are key mechanisms linking cathepsins to cell fate.
  • Extracellular cathepsins influence tumor progression via Extracellular Matrix (ECM) modulation, while intracellular cathepsins mediate Apoptosis.

Purpose of the Study:

  • To review recent advancements in Cathepsin research.
  • To highlight the mechanistic regulation of cathepsins in cancer.
  • To focus on the role of cathepsins in cell death pathways relevant to cancer.

Main Methods:
